Development and Validation of a Physical Activity Educational Module for Overweight and Obese Adolescents: CERGAS Programme

Abstract

Educational modules can be effective in educating and motivating adolescents to participate in physical activity (PA). This paper describes the development and validation of a PA educational module for use in an obesity intervention programme, CEria Respek Gigih Aktif Sihat (CERGAS). The present study was conducted in three phases: Phase I was composed of needs assessments with four focus group discussions to elicit adolescents’ opinions regarding module content and design, Phase II was the development of the PA module, while Phase III was content and face validation. A content validity index (CVI) was used to assess content validity quantitatively, with a CVI of more than 0.79 being considered appropriate. The needs assessments indicated that content of interest to adolescents included: the benefits of exercise; exercise techniques; ways to increase PA and how to stay motivated. Attractive graphic design was determined as a way to draw the adolescents’ attention. The module covered five topics: “Let’s Be Active”; “Exercise and Fitness”; “Staying Safe during Exercise and Physical Activity”; “Planning for Success” and “How to Overcome Sedentariness and Get Moving”. The module was found to have good content validity (mean CVI = 0.85). Expert members made suggestions to improve the module. These suggestions were then accepted, and the module was modified accordingly. We concluded that the module has good content validity and can be used to improve PA knowledge amongst CERGAS participants.

“…The experts examine each unit and give a value with a scale of 1 = not relevant, 2 = quite relevant, 3 = relevant, and 4 = very relevant. Furthermore, the assessment is based on a benchmark: (1) if the CVI is higher than 0.79, then the item is considered appropriate, (2) if the CVI is between 0.70-0.79, then the item needs to be revised, and (3) if CVI is less than 0.70 then the item must be eliminated (Lau et al, 2019).…”

“…The questionnaire data were analyzed to get the value of the Content Validity Index (CVI). Several studies use CVI in determining the validity of their products, including adult physical activity education modules (Lau et al, 2019), STEM modules for secondary schools (Kasim & Ahmad, 2018), basic statistics modules for prospective teacher students (Setambah et al, 2017), and problem-based training modules for nursing education students (Sathya & Reddemma, 2017).…”

“…The CVI value is considered to have good content validity if it reaches 0.80 or more (Rubio et al, 2003). CVI is calculated based on the number of experts who agree divided by the number of experts appointed (Lynn, 1986) (Rubio et al, 2003) (Lau et al, 2019). The expert recommendations state that at least five experts are involved in the validation process to avoid accidental agreements (Zamanzadeh et al, 2015).…”

Development and Validation of an Evaluation Tool to Measure the Effectiveness of a Smoking Cessation Training among Healthcare Providers in Malaysia: The Providers’ Smoking Cessation Training Evaluation (ProSCiTE)

“…The Content Validity Index (CVI) is extensively used in reporting the content validity of newly developed instruments [58,66,67,68,69,70,71,72]. In this study, the content validity of the developed instrument was statistically analyzed by an Item-Content Validity Index (I-CVI), a Scale-Content Validity Index (S-CVI), and kappa ( k ).…”

What to Do about Childhood Obesity?

“…Moving from identification of at-risk youth to education, two studies looked at methodologies for increasing physical activity. Xiao Lau et al created a physical activity module for adolescents based on focus groups with teens [15]. The teens identified key components of both content and presentation that could positively impact information uptake.…”
